Why is the E-Type's 50-Year-Old Design Still So Good?

If you ever run into someone that's a better-looking version of a person you had a crush on in high school, you can't help but be enthralled. Similarly, I'll always do a double take when I see a Jaguar E-Type, as my first car was a used Datsun 280ZX (not the exact one in the photo above, alas), whose predecessor 240Z owes a widely-acknowledged styling debt to the E-Type.
